Develop lithium battery fast charging technology -Lithium - Ion Battery Equipment
This year's "two sessions", Li Xiangbin, an "old acquaintance" of Hefei Public Transport, who was re-elected as the representative, focused on the field of new energy public transport. As an important position for new energy vehicles in the country, Hefei Bus has always been a signboard. "But there are still shortcomings in battery life, and the country should speed up research and development."
Hefei New Energy Electric Bus started early. As early as January 23, 2010, Hefei Bus Group opened 18 bus lines, which consisted of 30 pure electric vehicles, becoming the world's first pure electric vehicle bus line. However, Li Xiangbin, who works in the front line, also admitted that many years of operation have also exposed some shortcomings. The most troublesome thing is the battery life of the bus. The battery is large in size, slow in charging and low in stored power, which restricts the rapid development of new energy buses. "For example, a bus in Hefei needs to operate 300 kilometers per day, but the current battery mileage of new energy electric buses is about 250 kilometers. In case of traffic jams, it may only run 200 kilometers, and one line needs two cars to complete. It has greatly increased the operating cost." He suggested that the development experience should be summarized from the national level, several key enterprises should be organized in China, capital investment should be concentrated, and superior talents should be concentrated for R&D. Intensify research and development efforts on traction motors and frequency converters of pure electric vehicles, and develop motor equipment with less power consumption and greater traction, as well as power-saving and more efficient transmissions, so as to increase the cruising range of the battery.(Lithium - Ion Battery Equipment)
Li Xiangbin also found in the investigation that Ningbo, Hangzhou and other cities have piloted lithium battery fast charging, and the vehicle can be fast charged while waiting for passengers to get on and off, and can run an extra seven or eight kilometers. "The lithium battery fast charging mode is still in the research and development stage. It is hoped that the state can increase investment and speed up research and development efforts.
